    摘要： A method begins by a dispersed storage (DS) processing module obtaining a transaction number and generating a set of temporary write commands regarding storage of a data segment in a dispersed storage network (DSN) memory, where a temporary write command includes the transaction number, an encoded portion of the data segment, and an implicit instruction that the encoded portion is not to be stored or made accessible in accordance with a conventional manner. The method continues with the DS processing module transmitting the set of temporary write commands to the DSN memory. When the temporarily stored data segment is to be read from the DSN memory, the method continues with the DS processing module generating a set of temporary read commands, where a temporary read command includes the transaction number, identity of the encoded portion, and an explicit instruction to read the encoded portion in violation of the conventional manner.

    摘要： For each original data segment, a distributed storage processing unit generates encoded slices designed to prevent the original data segment from being reconstructed using fewer than a threshold number of encoded slices. Multiple encoded slices are generated for each of two different data segments, and the slices associated with the first and second data segment are stored substantially concurrently in different storage sets employing different distributed storage units. Encoded slices for even and odd data segments can be stored in different storage sets, or longer sequences of data segments can be stored in alternating storage sets. Storage sets can also be determined by the vault generation of a particular data segment.

    摘要： A processing module encodes data using a dispersed storage error coding function to produce a set of encoded data slices and identifies storage units for storage of the set of encoded data slices. The processing module determines that a storage unit of the storage units is unavailable, where the storage unit is targeted to store an encoded data slice of the set of encoded data slices. The processing module selects a foster storage unit of the storage units for temporarily storing the encoded data slice. When the storage unit is available, the processing module transfers the encoded data slice from the foster storage unit to the storage unit.

    摘要： A method begins with a set of storage units of a dispersed storage network (DSN) receiving a plurality of read requests for encoded data slices corresponding to particular content data. The method continues with a first storage unit detecting that a corresponding portion of the plurality of read requests exceeds a heavy load condition for the first storage unit. The method continues when the corresponding portion of the plurality of read requests exceeds the heavy load condition for the first storage unit with the first storage unit identifying a first alternative storage unit of the DSN. The method continues with the first storage unit sending a copy of the first group of encoded data slices to the first alternative storage unit and redirecting some of the corresponding portion of the plurality of read requests to the first alternative storage unit for processing.

    摘要： A method begins by a dispersed storage (DS) processing module receiving a file creation request to create a new file from portions of a set of existing files. The method continues with the DS processing module identifying data segments associated with the set of existing files corresponding to the portions of the set of existing files to produce identified data segments and identifying sets of encoded data slices of the identified data segments to produce identified sets of encoded data slices. The method continues with the DS processing module determining addressing information for the identified sets of encoded data slices from existing addressing information of the set of existing files and generating a segment allocation table for the new file based on the addressing information of the identified sets of encoded data slices such that the new file is created without duplication of the portions of the existing files.
